In this research, we hypothesize that post-operative monitoring implemented with a connected scale after the 1st year (weight nadir period) post obesity surgery (i.e. sleeve and RYGB) would reduce the percentage of patients with excessive weight regain (\>10% regain of lost weight) by improving the quality of follow-up and long-term results. To do this, we are carrying out a comparative study on 182 patients, controlled, randomized per patient, ratio 1/1, open, in two parallel arms. Patients will be followed for 12 months and divided into one of the following two groups: * Control group: Standard follow-up * Interventional group: Standard follow-up + weekly weighing with the "Body Comp Pro" connected scale During their follow-up period, patients in the intervention group will have to weigh themselves at least once a week using the "Body Comp Pro" connected scale. The information will be transmitted to the investigation team via a secure platform available 24 hours a day. Alerts will be generated from a weight regain \> 5% of the baseline weight, allowing early management of weight regain.

RECRUITINGCompare the percentage of patients with weight regain > 10% at 24 months post-operative in patients who have undergone obesity surgery (SG or RYGB) in the two groups of patients
Percentage of patients with weight regain \> 10% between inclusion (12 months post-op) and the 12-month visit (24 months post-op) in the two groups of patients
Time frame: 12 months from inclusion
To compare the weight change at 18 and 24 months post-operative in patients having undergone obesity surgery (SG or RYGB) in the two groups of patients
Weight change (in kilos and % of weight lost since the intervention) between the weight at inclusion (12 months post-op) and the weight at 6 and 12 months from inclusion (18 and 24 months post-op ) in both groups of patients.
Time frame: 6 and 12 months from inclusion
To compare the number of surgical reinterventions (planned or carried out) for weight regain at 24 months post-operative in patients having undergone obesity surgery (SG or RYGB) in the two groups of patients
Number of surgical reinterventions (planned or carried out) for excessive weight gain validated in a multidisciplinary consultation meeting between inclusion (12 months post-op) and the visit 12 months from inclusion (24 months post-op) in both patient groups
Time frame: 12 months from inclusion
To compare the evolution of comorbidities at 18 and 24 months post-operative in patients having undergone obesity surgery (SG or RYGB) in the two groups of patients
Resolution, evolution, recurrence, or occurrence of a comorbidity between inclusion (12 months post-op) and visits at 6 and 12 months from inclusion (18 and 24 months post-op) in the two groups of patients. The comorbidities identified are High blood pressure, Type 2 diabetes and sleep apnea syndrome
Time frame: 6 and 12 months from inclusion
To compare anxiety and depression at 18 and 24 months post-operative in patients having undergone obesity surgery (SG or RYGB) in the two groups of patients
Evolution of the HAD scale score between inclusion (12 months post-op) and visits at 6 and 12 months from inclusion (18 and 24 months post-op) in the two groups of patients
Time frame: 6 and 12 months from inclusion
Compare the quality of life at 18 and 24 months post-operative in patients having undergone obesity surgery (SG or RYGB) in the two groups of patients
Evolution of the SF-36 quality of life score between inclusion (12 months post-op) and visits at 6 and 12 months from inclusion (18 and 24 months post-op) in the two groups of patients
Time frame: 6 and 12 months from inclusion
Compare the number of lost to follow-up at 18 and 24 months post-operative in patients having undergone obesity surgery (SG or RYGB) in the two groups of patients
Number of patients lost to follow-up between inclusion (12 months post-op) and visits at 6 and 12 months from inclusion (18 and 24 months post-op) in the two groups of patients
Time frame: 6 and 12 months from inclusion
To compare the change in body composition measured by a connected scale at 18 and 24 months post-operative in patients having undergone obesity surgery (SG or RYGB) in the two groups of patients
Evolution of body composition (muscle mass, fat mass) measured by the connected scale between the inclusion visit (12 months post-op) and the visits at 6 and 12 months from inclusion (18 and 24 months post-op ) in both groups of patients.
Time frame: 6 and 12 months from inclusion
For interventionnal group only : Evaluate the impact of the use of a connected scale on the consumption of additional care at 18 and 24 months post-operative in patients having undergone obesity surgery (SG or RYGB).
Number of telephone calls, consultations or hospitalizations in hospital, secondary to an alert generated by the connected scale between the inclusion visit (12 months post-op) and the visits at 6 and 12 months of inclusion (18 and 24 months post-op) for each patient in the interventional group
Time frame: 6 and 12 months from inclusion
For interventionnal group only : Evaluate adherence to the use of a connected scale at 18 and 24 months post-operative in patients having undergone obesity surgery (SG or RYGB)
Average frequency of use of the connected scale between inclusion (12 months post-op) and visits at 6 and 12 months from inclusion (18 and 24 months post-op) for each patient in the interventional group compared to this which is required of them (i.e. 1 weighing per week)
Time frame: 6 and 12 months from inclusion
